Specimen dimensions to ISO 148-1. The ISO 148-1 standard specifies the dimensions for a so called normal specimen: Length: 55 mm. Width (designation in ISO 148 Series prior to 2016 was “height”): 10 mm. Thickness (designation in ISO 148 Series prior to 2016 was “width”): 10 mm.
1.1 These test methods describe notched-bar impact testing of metallic materials by the Charpy (simple-beam) test and the Izod (cantilever-beam) test. They give the requirements for: test specimens, test procedures, test reports, test machines (see AnnexA1) verifying Charpy impact machines (see AnnexA2),
Objectives: To study the impact resistance of metals using impact testing machine of the Charpy type. To determine the variation of impact strength of a material with change in temperature.
Foreword. The standard EN 10 045 concerns metallic materials — Charpy impact test and comprises the following parts: — Part 1: Method of test; — Part 2: Verification of pendulum impact testing machines. Part 1 of EN 10 045 is based on the following ISO Standards: ISO 83-1976, Steel — Charpy impact test (U-notch).
Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3).
The most common configuration for pendulum impact test are Izod and Charpy ones. The scope of these impact test is to measure the answer of a standard test specimen to the pendulum-type impact load.
Plastics — Determination of Charpy impact properties — Part 1: Non-instrumented impact test 1 Scope This document specifies a method for determining the Charpy impact strength of plastics under defined conditions. A number of different types of specimen and test configurations are defined. Different test
